Title: Sheet positioning and selecting apparatus
IPC: G06K13/063
Filed: 1965-11-03
Abstract: 1,096,710. Filing papers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 3, 1965 [Dec. 17, 1964], No. 46488/65. Heading B6E. [Also in Division G4] In apparatus comprising means for selecting any one card or sheet from a store of cards or sheets, the selecting means includes devices which produce across the surfaces of a selected card an air flow tending to maintain the card in a predetermined plane. As described, the arrangement is employed in a random access memory system (Fig. 1) wherein magnetic record cards 14 are disposed radially in a drum (16) which can be rotated under the control of a data-processing system (24, 22) to position a selected card adjacent to withdrawal mechanism (30) by means of which the card is passed over a cylinder (32) associated with a record reproducing assembly connected to read-write circuits (33). The cylinder (16) has subcells formed by springs 23, Fig. 2, between which a set of cards with individual tabs 20 is held. When a selected card is positioned adjacent to the withdrawal mechanism (30), wedges 40, 41 are operated to move the springs 23 apart to release the cards in the subcell. At the same time, separator arms 36, 38 engage the tabs 20 of the cards immediately adjacent to the selected card to force these cards apart and leave the selected card exposed. This separation is facilitated by forming the ends 38 of the separator arms as air jets. The air flow across the card is caused by the application of suction to orifices 42, 43 in the wedges 40, 41. The orifices are positioned symmetrically with respect to the desired plane of movement of the card and the air flow causes the card to be moved into that plane if it deviates therefrom, so that it is accurately positioned with respect to the withdrawal device (30). The withdrawal device (30) engages a central aperture 21 in the card to remove the card from the drum 16. Reference has been directed by the Comptroller to Specification 918,582.

Title: Input/Output Control for a Digital Computing System.

Abstract: 1,191,560. Computer input/output. BURROUGHS CORP. 4 Oct., 1968, No. 47311/68. Heading G4A. In a computer system, an associative memory containing peripheral unit designators is used to address a buffer memory, data being transferred between the buffer memory and a peripheral unit. Input-Output.-An initiate signal from a central processor causes a peripheral control multiplexor to obtain an I/0 descriptor from main core memory and store a peripheral device (input, output, or bulk storage) designator from it in the first free row of an associative memory and store the whole descriptor (after repositioning of fields) in the corresponding row of a buffer memory in the multiplexor. An operation code from the descriptor is also sent to peripheral control units associated with respective peripheral devices, the one selected by a decoding of the device designator responding by sending an access request signal to the multiplexor on a respective line when it is ready. The highest priority access request is encoded to provide a (device designator) tag to interrogate the associative memory, and the row of this giving a match reads out the word in the corresponding row of the buffer memory to a word register, a character of data being transferred between this word and a register in the appropriate peripheral device control unit. The word from the buffer memory contains a main memory address, a word count, a character count and has 8 character positions for data. The characters in the character positions are shifted along while the word is in the word register so that a character from the peripheral device control unit can be inserted into the rightmost position or supplied to the peripheral device control unit from the leftmost position according to the direction of transfer. The character count is incremented after each character transfer and the word restored into the buffer memory (permitting an access request from a higherpriority peripheral to be serviced). When the character count indicates the 8 character positions are full (on input) or empty (on output), an 8-character data word is transferred between the word register and the main memory address specified by the buffer memory word, in the appropriate direction. This address is then incremented, the word count decremented, and the character count reset to zero. When the word count reaches zero (end of operation) the appropriate row of the associative memory is cleared. The initial values of the main memory address and word count in the buffer memory word came from the descriptor. Access requests (see above) from the peripherals have priority over initiate signals (see above) from the processor in use of the associative memory.

Abstract: 479,883. Cables. STANDARD TELEPHONES & CABLES, Ltd. Aug. 14, 1936, No. 22464. Convention date, Aug. 17, 1935. [Class 36] A power cable has its insulation divided by at least one conductive or semi-conductive fluid-tight equipotential layer into one or more inner portions and an outer portion, the inner portion or portions being maintained under high pressure by a pressure fluid which also acts outwardly on the outer portion whereby this portion is maintained under a pressure which is lower than that in the inner portions and which decreases towards the periphery of the cable. The inner portion or portions must always contain a fluid to take up the pressure, which fluid may be the pressure fluid itself or an additional fluid. The outer portion of the insulation may be made of strong paper, rayon products, vinyl compounds, or other strong material to avoid the necessity of reinforcing the cable against the internal pressure. The equipotential layers may consist of metal foil, conducting or semiconducting rubber compositions, or vinyl compounds provided with a conducting surface. Fig. 1 shows a cable in which the inner portion 2 of the insulation is subjected to high oil or gas pressure and is separated from the outer portion 4 of the insulation, which may be made according to the principles of a mass cable or an oil cable, by a fluid-tight equipotential layer 3. In a multicore cable with belt insulation, Fig. 2, the individually insulated cores 1 may be each surrounded by an equipotential layer 3 whilst another equipotential layer 5 is disposed on the inner surface of the belt insulation 4. Either each layer 3 or the layer 5 is fluid-tight and the portion or portions of the cable within the fluid-tight layer or layers are maintained under high pressure. In the constructions shown in Figs. 5, 6 and 9, spaces 8, which house the pressure fluid, are provided between an equipotential layer or layers 3 surrounding the inner portion or portions of the insulation and a fluid-tight equipotential layer 5 arranged on the inner surface of the outer portion 4 of the insulation. The layer 3 is permeable in the construction of Fig. 5, but fluid-tight in the embodiments shown in Figs. 6 and 9.
